Enteric capsules, also known as extended-release capsules are specially designed to withstand the acidic environment of the human stomach during the digestive process until they reach the next stage of digestion. Enteric capsules are coated with a substance that prevents or reduces disintegration in the stomach, allowing it to dissolve in the small intestine. This formulation protects the stomach from potentially irritating drugs and protects the medicine from a partial breakdown in the stomach's acidic environment.

Types of Enteric Capsules

000 Enteric Capsule
The Empty 000 Enteric Capsule is a type of capsule that is empty on the inside and has an enteric coating. The enteric coating is designed to protect the contents of the capsule from stomach acid, thus ensuring that they are released in the small intestine. This results in better absorption and bioavailability of the contents.
Enteric Coated Capsule Size 4
Enteric coated capsules are ideal for supplements that are highly acidic and can cause discomfort or irritation when ingested. Enteric coating is a polymer layer that surrounds the capsule and prevents it from dissolving in the stomach. Enteric coated capsule size 4 is a popular choice for dietary supplements.


Size 5 Enteric Capsule
Size 5 Enteric Capsule is an advanced drug delivery system used for encapsulating drugs and dietary supplements. The capsule's enteric coating ensures that it dissolves only in the intestines, preventing the drugs/supplements from being released in the stomach. This results in maximum absorption and minimal stomach irritation, making Size 5 Enteric Capsules ideal for people with sensitive stomachs.
Enteric Capsule Size 1
Enteric capsules are the ultimate solution for delivering drugs and nutrients directly to the targeted area in the digestive system. This is done by using a type of coating that protects the capsule contents in the stomach and releases them once it reaches the small intestine, where absorption occurs. Among the various sizes of enteric capsules, Size 1 is the most popular one.

Advantages of Enteric Capsules
Do not irritate the stomach
Many common drugs, such as aspirin, can irritate the stomach. Because they pass through the stomach intact, Enteric Capsules avoid this problem.
Preserve enzyme activity
Most tablets break down in the acidic environment of the stomach. Unfortunately, depending on the product’s formulation, this acidic environment can also negatively impact the desired enzyme activity. Enteric Capsules protect the enzymes so that they can be absorbed, at their highest activity levels, in the small intestine.
Take longer to dissolve
While most capsules dissolve within 15 minutes, Enteric Capsules do not break.
Applications of Enteric Capsules
Pharmaceuticals
They are commonly used for medications that are sensitive to stomach acid, such as certain anti-inflammatory drugs and antibiotics.
Functional Foods
Some functional foods integrate enteric capsules for encapsulating flavors or bioactive compounds, enhancing the overall health benefits of the product.
Dietary Supplements
Many health supplements utilize enteric capsules to deliver probiotics and enzymes, ensuring that these beneficial ingredients are released in the intestines where they can act effectively.
Nutraceuticals
Enteric capsules help in providing an effective delivery system for vitamins and minerals that improve nutrient absorption while minimizing gastrointestinal discomfort.
Enteric Capsules Components

Enteric capsule polymers
Enteric capsules are built using polymers. They serve as the principal defense against the stomach's severe circumstances. Enteric capsule commonly employs cellulose acetate phthalate (CAP), hydroxypropyl methylcellulose phthalate (HPMCP), and polyvinyl acetate phthalate (PVAP).

Enteric capsule plasticizers
To increase the polymer's flexibility and adherence, plasticizers are added. They aid in the adhesion of the coating to the tablet's surface and its integrity during the manufacturing process. Plasticizers often utilized in Enteric capsule include triethyl citrate, dibutyl sebacate, and diethyl phthalate.

Enteric capsule solvents
Solvents are utilized to dissolve the polymer and plasticizer, resulting in a uniform coating solution. Methylene chloride, acetone, and ethanol are common solvents used in Enteric capsule. The solvent chosen is determined by the solubility of the polymer and plasticizer, as well as their compatibility with the medicinal ingredient.
Enteric Capsules Coating Processes And Steps
Coating Solution Preparation
This is the first stage in any enteric coating process. The coating solution is often a mixture of polymers, plasticizers, and other additives. To guarantee a homogenous solution, the coating solution is made in a big tank or a machine like the Tablet Coating machine BG-660E and well mixed.
Curing the coated pills
The next stage in an enteric coating process is curing the tablets, which entails exposing them to high temperatures for a set period. This procedure improves the coating's endurance and ensures that it can tolerate the acidic environment of the stomach without degrading.
Coating Solution Application
After preparing the coating solution, the tablets are loaded into a coating pan, which is typically a spinning drum. The coating solution is then sprayed onto the tablets with a spray nozzle, resulting in a thin and uniform coating layer.
Drying the coated pills
After applying the coating solution, the tablets are dried with a hot air stream. This step is critical for removing any moisture from the coating and ensuring appropriate coating adhesion to the tablet.
